I did this. It's free and just send it back and fill out some surveys. they also tell you your ancestral line and connect you via their online community to your relatives. they found some of my third, fourth and fifth cousins.

i had negative side effects to it, although I am in the 1%. It pretty much temporarily wrecked my bone marrow, knocking my blood cells down to half what they should have been. I felt like passing out every time i moved

You should probably have a reason for making the video. As in...what are you trying to accomplish? a walkthrough? tutorial? gameplay? You want to have some kind of story in mind. Gather footage that will tell a compelling story, and edit it together. Maybe you want to show an assault on the ship. gather footage from different angles and edit it together. Be sure to have a beginning, middle, and end. The music doesn't set any kind of mood. scrap the music all together and find something more fitting. include ambient sound, and voice over. wash, rinse, repeat.
